We handle basement waterproofing, sump pump installation, and vapor barrier work so you get a dry foundation without mold risk, typically finished in under a week.
Family-Owned and Locally Trusted
Every time it rains, you check. Water stains on the wall. Puddles collecting near the floor. That damp smell that never quite disappears. You know it’s more than cosmetic.
The longer it sits, the worse it becomes. Mold begins to spread. Wooden beams weaken. Repairs turn expensive. And the space that should add value to your home becomes a problem you can’t ignore.
NH Dry Basement LLC is a family-owned business that has helped Manchester homeowners protect their basements from water damage. We focus on honest work, clear communication, and showing up when we say we will.
Our team handles basement waterproofing, crawl space drainage, sump pump installation, vapor barrier work, and dehumidification. We dig the trenches, set the pumps, seal the crawl spaces, and install the systems that keep water out. Every job is done by people who live and work in this area.
We treat each basement like it belongs to a neighbor, because it usually does. Your Manchester home deserves a dry foundation that lasts.
Homeowners dealing with foundation leaks get perimeter drainage, sump pumps, and vapor barriers that stop water intrusion for good.
Permanent drainage keeps water out through every storm, so your basement stays comfortable no matter the season.
Vapor barriers and dehumidification eliminate musty odors and reduce mold risk before it spreads through your home.
Proper waterproofing stops structural damage early, preserving your foundation and protecting long-term resale value.
Our basement stayed dry through the last two major storms, something we haven’t been able to say in years. The crew walked us through every step, answered all our questions, and cleaned up after themselves every single day. The new drainage system and sump pump have given us real peace of mind.
They fixed a crawl space drainage problem three other contractors said was too complicated. The difference in our air quality upstairs is noticeable.

We install interior channels around the entire foundation so water moves into the sump before it touches your floor.
Storms cut power when you need pumps most, so battery backups keep the system running through heavy rain.
We seal crawl space floors with thick polyethylene overlapped at every seam to block ground moisture and mold growth.
Pumps are matched to your property's water volume so the basin handles heavy flow without constant cycling or overflow.
We compact gravel bases and route drainage before pouring so new concrete slabs sit on stable ground with zero settling.
We position commercial dehumidifiers where air circulates best, pulling moisture out faster and preventing musty odors from returning.
From waterproofing to drainage systems, we handle moisture control across the region. Every job uses materials chosen for New England’s freeze-thaw cycles and heavy spring runoff.
Most interior drainage and sump pump installs finish in one to three days. Projects involving crawl space encapsulation or exterior excavation may take longer depending on access and weather.
Yes. We handle sump pump installation, battery backup systems, and automatic float switches. Adding a backup protects your basement during storms when power goes out and the primary pump can’t run.
Yes. We install vapor barriers, drainage channels, and dehumidifiers without sealing vents if you prefer partial protection. Full encapsulation offers better long-term moisture control, but targeted fixes work for many homes.
We document the affected area, explain the source of moisture causing the growth, and recommend safe removal steps. Our drainage and vapor barrier work addresses the root cause so mold doesn’t return.
Run it continuously during humid months. Set the target humidity between 50 and 55 percent. Empty the reservoir or check the drain hose weekly to confirm steady operation and prevent overflow.
